GASBOY Series 9820Q12 MDE-4339 9820Q ASTRA Installation/Operation • July 2004

Control Lines3. Control LinesPurposeThis section is provided to familiarize the installer with the control inputs and outputs that areavailable for the Series 9820Q. It is recommended the installer read these descriptions to obtain abetter working knowledge of the unit in order to guide him in planning the site wiring. ReferenceSection 4 for a specific wiring diagram and installation notes.The Series 9820Q may be provided for use with 230 VAC power for international applications.The operating voltage for control lines to these units is shown in parentheses as (230 VAC Int'l).If connecting the 9820Q to a GASBOY fuel management system, refer to the appropriate fuelmanagement system Installation Manual for detailed installation information.GroundTo ensure proper operation of the equipment and provide the necessary safety factors, a goodground line must be provided. A ground wire (preferably green) must be connected between theground screw of the register and the main electrical service panel. One (1) earth groundconnection is required per unit. The ground rod is to be a solid, corrosion-resistant conductor andmust be installed at the main electrical panel in accordance with the National Electrical Code. Itshould be properly tied into the ground bus strip of the panel. We recommend the neutral andground bus strips be bonded together (unless prohibited by local codes).Micro FeedThe Micro Feed is a 115 VAC (230 VAC Int'l) input required to power the microprocessor of theregister's electronics. This power must always remain on and must be on a separate breaker fromthe control lines (Pump Motor Feed). In a site configuration using multiple units, the power for themicroprocessors of up to 8 units can be supplied by one breaker.Micro NeutralThe Micro Neutral is a return line for AC current from the microprocessor of the dispensing unit tothe breaker panel.Pump Motor FeedThe Pump Motor Feed is a 115VAC (230 VAC Int'l) input which is required to power the pumpand authorize the control line. This line is used to provide authorization for the unit (when enabledthrough the DIP switches). If this line is controlled by a fuel management system using solid staterelays, a resistor assembly must be installed between the Pump Motor Feed line and Feed Neutralto prevent false triggering of the authorization input. The resistor assembly is 8.2K OHM, 10 Watt(P/N C05818) for 115/230 VAC domestic and 30K OHM, 10 Watt (P/N C06683) for 230 VACinternational wiring.The Pump Motor Feed line is used to power the slow flow and fast flow valves (when installed).The power used to control the pump is also provided by this line. The Reset Complete signal usedfor external monitoring of the pump originates from the Pump Motor Feed line.MDE-4339 9820Q ASTRA Installation/Operation • July 2004 13
